BSNL was planning to replace its Linux based proxy server with a Firewall and Web
Content Filtering solution for its corporate office in Delhi.
Cyberoam provides excellent
content filtering solution. With
more than 82 categories and
more than 44 million websites,
it provides unmatched flexibility
and control over the online
activities of the users.
Ms. Jeena Pal
BSNL has two ISP connections BSNL and AIRTEL, in its headquarters and it had
Linux based proxy servers. While the Linux based proxy servers failed to do any sort
of web content filtering, the load balancing and failover for both the ISP links, was also
a tedious manual process.
The Technical Director at BSNL, Ms. Jeena Pal, outlined BSNL‘s requirement thus,
“We had no control over our employees‘ surfing habits. This led to multiple problems.”
- Loss of productivity
- Bandwidth wastage
- Potentially harmful surfing opened flood gates for web based malware to sneak
into the corporate office network and spread mayhem.
- High frequency of help desk calls for the IT department
- The multiple ISP links were manually managed. There was no load balancing
and in case of a WAN link failure, the traffic had to be manually redirected.
“We were looking for a single box solution to all our problems, Something that will ac
as a panacea. So far we were well acquainted with Cisco products. But when it came
to such issues related to productive security, Cisco did not fit in,” Ms. Pal said.
The Cyberoam Solution
BSNL had an easy familiarity with Cisco as most of the hardware came from it. So
their first choice was Cisco ASA. Once they had gone through its specifications, Ms.
Pal decided to look at non-Cisco products as she found ASA‘s scope limiting. Rather,
putting it the other way; Cisco did not meet their requirements.
They decided to deploy appliance-based, indigenously designed
Management (UTM) solution - Cyberoam. They installed one 500i in the corporate
office and one 250i in a strategic branch office nearby. Both the appliances were
installed in Gateway mode. In the corporate office, both the ISP links were terminated
on Cyberoam to facilitate link load balancing and gateway failover. Cyberoam acts as
a firewall and controls the access to various network resources. Cyberoam‘s firewall is
certified by ICSA and Checkmark.
Cyberoam‘s web filtering database which is 44 million website strong is divided into 82+
categories to facilitate flexibility. As soon as the appliance was in the network, the
uncontrolled surfing stopped. Cyberoam ensures that all unproductive and potentially
dangerous surfing is denied. Malware laced sites are all blocked and no unauthorized
downloads are permitted.
BSNL has created Virtual Hosts to allow multiple servers in the DMZ to be accessed
using multiple Public IP Addresses. This enables balancing the traffic among multiple
Multilink management feature of Cyberoam now shoulders the load balancing between
both the links. The failover feature ensures that if any one of the link fails, the entire
traffic is seamlessly shifted to the other functioning link. Once the down link gets
restored, the load balancing feature kicks in without any manual intervention and status
quo is restored.
Cyberaom‘s On-Appliance reports provide Ms. Pal with perfect visibility of all the
surfing habits and network events. This helped her identify the potential rule-breakers
and stop them in their tracks. Knowledge enabling pre and post sales technical
assistance from Cyberoam is aimed at empowering the customer to be self sufficient.
Rounding up the discussion, Ms. Pal said, “Cyberoam‘s user-friendly and intuitive
interface and comprehensive Web content filtering ensures that all the employees at
the BSNL headquarters are productively focused.”
